What are others seeing for co2 levels while sleeping?
I am curious what others with PGH houses are seeing for co2 levels while sleeping. I recently got a Aranet4 (calibrated it) and just began getting some data for a few days. I am peaking at just over 1000 ppm early in the morning just before getting up. My house seems to generally be at low 700’s most of the day. I am generally sleeping well but now that I see the data I wonder if I could be waking more well rested. I’ll list some details below:
Less than 1 year old PGH build – 1900 sqft
Broan AI ERV (current settings: 50 cfm Continuous – 119cfm Boost)
Lots of boost events happen in a day, I’d guess 4+ hours a day are boost levels
I use “boost” for light cooking and bathroom use (range hood with MUA for serious cooking)
2 adults and a large dog (dog sleeps in bedroom too)
NO combustion appliances
This is my 3rd high performance house (I am a builder) and have always been on team “don’t over ventilate” although as more IAQ data comes out I am leaning towards turning things up a bit but I also don’t want too much of an energy penalty.
(one option for my ERV is to schedule a “Boost” event once late in the night)
